The wigs, that is: The reliably beautiful women of Montreal’s annual Salon Son et Image have, for 2013, traded their signature blue wigs for blue slacks and a trace of blue hair dye. This morning they showed off their fetching new look while looking for and fetching my press badge, just two hours before the start of the show’s trade day. Salon Son et Image, at the Montreal Hilton Bonaventure, opens to the public on Friday, March 22, and runs through Sunday.
